Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine-2,2,3,3-d4 (CAS 1949816-54-9) is a high-purity analytical reference standard with the molecular formula C8H3D4BrO2 and a molecular weight of 219.07 g/mol.
The molecular framework of 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine-2,2,3,3-d4 (C8H3D4BrO2) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine-2,2,3,3-d4 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
